The activity filter
In the Customer 360, we built the activity filter to allow users to only see a subset of activities that are logged against a customer's profile. This helps you quickly find a specific topic or interaction types within the profile history.
Why can't I see my activities?
In 90%+ of the cases, it's because you've selected a filtering that hides the activity you're looking for. If you can't see any activities, it's likely because you checked the "Only Starred" checkbox when you don't have any activities starred. If this still doesn't resolve it, then try de-selecting all boxes (e.g., email, chat, Success Plan) and re-select them again.
Note that this filtering is "permanent": if you set it at one customer profile, and then move to another, the same filter will apply. If you remove a filter, it'll be removed from all of your views.
